Most people treat MCP and AI Agent Skills as separate choices

📌 When to use MCP:

1\ You want plug-and-play integrations across services  2\ You need standardized tool access across multiple agents  3\ You’re building a shared tool ecosystem at scale

📌 When to use Agent Skills:

1\ You want structured, repeatable behavior  2\ You need domain specialization (e.g., a code generation skill)  3\ You want controlled, predictable execution logic

So, if AI Agent skills can call MCP, do we really need to connect it?

Yes, because Skills decide when and why to call a tool, but MCP decides how the connection actually happens.

Skills without MCP = a brain with no arms.  MCP without Skills = arms with no brain.
